Product Description

Motor Mount Set, Poly 75D – BMW E28 (535, M5)

Motor Mount Set, Poly 75D for BMW E28 535, M5. The stock motor mounts deflect as torque moves through the drivetrain, allowing the motor and trans assembly to move. These straight bolt-through polyurethane motor mounts will eliminate virtually all of the movement of the engine under load – increasing power transfer to the rear wheels. Our exclusive design incorporates the factory offset position necessary for a proper fit, consists of multiple parts and is fully rebuildable. Proper heat-shielding is required on the right side mount. The material used for the trans mount location(s) must match the material used for the engine mounts. For dedicated race/track cars, pair with our Poly 75D Trans Mount Set #TM3036. For dual purpose cars, or where NVH is a consideration, pair with our Performance Trans Mount Set #TMU3036.

These extremely hard race-spec 75D durometer polyurethane motor mounts are the hardest available (aside from solid aluminum) and the best option for race classes where solid mounts are not allowed, or for those who do not wish to deal with the issues that may arise when using solid mounts.

Our U.S. Military Spec 75D durometer compound is as hard as a bowling ball, yet has elasticity and memory. This exclusive compound allows us to manufacture a mount that has virtually the same performance as a solid motor mount without the harshness on the brackets/chassis associated with solid mounts. Likewise, its elasticity and memory means they are also free from deformation which plastic mounts (Delrin, UHMW) are very prone to.
